Eine Forschergruppe unter der Leitung von European XFEL-Wissenschaftlern hat eine neue Methode eingesetzt, um sich schraubenförmig ausbreitendes - oder zirkular polarisiertes - Röntgenlicht zu identifizieren und zu messen, dessen Anwendung neue Gebiete der Chemie und anderer angewandter Wissenschaftsbereiche erschließen könnte. Das Verfahren wurde erstmals im Forschungszentrum Elettra Sincrotrone am Freien Elektronen Laser FERMI in Triest getestet, der derzeit einzigen Anlage der Welt, an der so intensives und polarisiertes Laserlicht zur Verfügung steht. Die Arbeit, an der auch Wissenschaftler von FERMI, DESY und anderen Forschungseinrichtungen beteiligt waren, wurde heute im Online-Journal Nature Communications veröffentlicht.
